1. What patterns, if any, do you see in your data? On your position vs time graph?
2. What does this pattern say about the motion you observed?
3. If you look at a particular time, say, 20 seconds, how do each of your trips compare? Does this make sense? Why?
4. Draw a best-fit line through the data points for each of your trips. Calculate the slope of each line. What are the units of these slopes.
5. What does the slope each trip's data tell you about the trip?
6. Based on your analysis, what is the physical significance of the slope of a position vs time graph?
